277VAC 150W Constant Voltage LED Driver Manufactuers with UL certification
Our 277VAC Constant Voltage LED Driver compliant with worldwide safety regulations for lighting, it is certified to USA / Canadian Standards and is compliant to the strictest Electrical Safety Codes.
The iP67 150w led driver provides a constant Voltage of 12V DC and feature two distinct ports for input and output: the 120V AC/277v AC input (black wire) has 3 wire connections: one for the live wire (black), one for the neutral wire (white) and one for the ground (green). The 12V DC output (white wire) features 2 connections: one positive (red) and one negative (black).
